2 Claims.

This invention relates to a steam deflector that is designed primarilyfor use on the exhaust nozzle of a locomotive.

At the present time there is available to the 5 public deflectors ofthis general type, but with deflectors of now known designs considerabledifficulty and inconvenience is being experienced by those utilizingthese deflectors in that a back pressure to an undesirable high degreeis set up in the steam, and the deflector does not properly function todiffuse the steam over the entire cross sectional area of the stackextension and smoke stack.

With the inefficient results afforded by the now-known deflectors ofthis type in mind, this invention has in view as its foremost objectivethe provision of a steam deflector for the exhaust nozzle of alocomotive, which will be effective to thoroughly diffuse the steamthroughout the entire stack extension and smoke stack, at the same timereducing back pressure in the steam.

In attaining this end the invention proposes the use of a ring which isintended to constitute the nozzle tip, and which is carried by thenozzle, and which ring carries a plurality of deflecting elements in theform of triangular or tooth shaped members which project into the nozzleopening. When a nozzle is provided with such a tip having an appropriatenumber of deflecting elements, say for instance four, its use isattended by the following advantages:

The exhaust steam coming from the nozzle completely fills the smokestack, and as a result the vacuum in the smoke box is greatly improved,thereby insuring a complete and more eflicient combustion of fuel. Dueto the fact that back pressure on the. steam is decreased, theconsumption of water in the running of the locomotive is correspondinglylessened, and this decrease in back pressure of the steam also affordsthe advantage of having less wear on the rod bushings. Also due to themore perfect combustion of the fuel afiorded by the proper diffusing 5of the steam, it is possible to obtain a higher degree of super heatfrom the fuel.

A further advantage of the present invention is that its cost ofinstallation is comparatively cheap, and readily carried out on thesteam ex- 50 haust nozzles of locomotives without undue trouble.

Various other more detailed objects and advantages will in part becomeapparent, and in part be hereinafter stated, as the dBSCIiPtiOn of 55the invention proceeds.

The invention, therefore, comprises a steam deflector for the exhaustnozzle of locomotives consisting of a ring carrying a plurality ofdeflecting elements in the form of triangularly shaped membersprojecting into the nozzle opening, with the 5 points of the trianglesnearest to the center of the opening.

For a full and more complete understanding of the invention, referencemay be had to the following description and accompanying drawing,wherein Figure l is a view in plan elevation of a ring carrying thedeflecting elements, in accordance with the precepts of this invention,

Figure 2 is a side View, partly in section, and partly in elevation,showing the manner in which the ring and deflector elements of Figure lare mounted on a steam exhaust nozzle, and

Figure 3 is a detailed view in perspective of one of the deflectingelements. 20 7 Referring now to the drawing, wherein like referencecharacters denote corresponding parts,

a portion of a steam exhaust nozzle is shown in Figure 2, andrepresented by the reference character Ill. The exhaust nozzle I0 has anozzle 25 opening designated II. A ring, which is identified at I2, iscarried by the nozzle I0, and may be afiixed thereto in any preferredmanner, such as by the headed bolts shown at I3.

A deflecting element is shown at Figure 3, and identified by thereference character I 4. This deflecting element is of a triangularformation, as illustrated, having converging sides I5 which terminate ina point I6.

The ring I2 carries a desired number of deflecting elements I4. In theillustrated embodiment of the invention, the. ring I2 is shown ascarrying four of these deflecting elements, al-

though obviously this number may be varied, as 40 occasion demands. Thedeflecting elements I 4 may be attached to the ring I2 in any approvedmanner, and in the form of the invention shown in the drawing, each ofthe deflecting elements is shown as having an extension I! provided withopenings I8 through which pass screw fastening elements designated I9.

Steam coming from the opening II of the nozzle II] will strike againstthe deflecting elements I4, and be diffused in a highly efficientmanner, as above pointed out. Due to the fact that the cross sectionalarea of the opening I I is only slightly reduced by the deflectingelements I4, the back pressure created by these deflecting elements iscomparatively small. At the same I time proper diffusing action in thesteam is obtained.

While a preferred specific embodiment of the inventionis hereinbeforeset forth, it is to be clearly understood that I am not to be limited tothe exact construction illustrated and described, because variousmodifications of these details may be provided in putting the inventioninto practice within the purview of the appended claims.

We claim:

1. A steam deflector for the exhaust nozzles of locomotives comprising aring member, a plurality of fiat pointed tooth shaped deflectingelements carried by the ring member, a flat face of each deflectingelement being fastened to a flat face of the ring member, each toothshaped deflecting member having its point extending into the opening ofthe ring member, and means for affixing each of the tooth shapeddeflecting elements to the ring member.

2. A steam deflector for the exhaust nozzles of locomotives comprising aring member having a flat surface, a plurality of flat pointed toothshaped deflecting elements carried by the ring member with a flat faceof each deflecting element being fastened to the flat face of the ringmember, each tooth shaped deflecting element projecting inwardly fromthe said ring member with the portion of the deflecting element whichextends beyond the ring member being substantially triangular information with the apex of thetriangle disposed nearest to the center ofthe ring member and the base of the triangle being defined by the inneredge of the ring member, and means for affixing each of the tooth shapeddeflecting elements. to the ring member.
